Viral Vectors Essay

Gene therapy is a very controversial topic that has been discussed in the last five years and is being heavily studied to help cure cancer. Gene therapy is a technique aimed at treating genetic disorders by introducing the correct form of the defective gene into the patient’s genome (Dunlop et al., 2010).

One side to this issue is the use of viral vectors in gene therapy to cure the underlying disease. One of the first viral vectors used was the adenovirus vector. The adenovirus by itself is a linear double-stranded DNA molecule that causes mild respiratory infections, but when used as a vector, certain genes and regions are removed to make it less harmful (Alton, et al. 2010). The adenovirus vector is easy to grow, adaptable, able to infect both dividing and non-dividing cells and is quick to

ANS: They found that chloroquine treatment did protect neuritis from becoming misshapen or damaged. It also showed that exposure to chloroquine the number of neuritis infected decreased as well.

Technology has advanced greatly in the last decade, everyday scientists are developing techniques to cure diseases. Millions of people die every year due to harmful diseases with no cure. The term virus holds a negative meaning to humans. However, scientists are now able to manipulate viruses in a beneficial way. The Talimogene Laherparepvec virus, which came from herpes, has been genetically modified in order to treat melanoma patients (Ledford, 2015).

Roughly fifty years ago, scientists thought that the use of genetic modification by exogenous DNA would be effective. This idea could offer curative and long lasting benefits, in a single treatment.

Whether gene therapy should be allowed to be used in practice is currently a very controversial topic. In my opinion, I do not think that it should be allowed. Gene therapy is a technique where genetic material is inserted into a patient to replace missing or defective genes. Gene therapy can be further broken down into two categories: somatic and germline. From there, somatic gene therapy can be approached in two ways: in-vivo and ex-vivo. For the process of gene therapy to begin, the proper vector needs to be acquired. Once a vector is chosen, the vector delivers the new gene into the target cell. Then, the target cell becomes infected with the vector. Next, the vector’s genetic material is inserted into the target cell. Then finally, functional

There are two types of gene therapy; germline gene and somatic gene therapy. Germline gene therapy is considered to be a safer option for humans. This method makes changes to the gamete cells that are used in the reproductive process thus, the functional genes need to be inserted into the chromosomes. Somatic gene therapy is when genes are transferred to body cells by inserting vectors into a person’s body. There are three things that gene therapy can do; replace a mutated gene that causes a disease with a healthy gene, deactivate a mutated gene that is not able to function properly, or introduce a new gene into the body to prevent diseases. There has been a clinical trial in the past where over 3000 people were treated with gene therapy and the results were good however, this treatment method has serious health

Gene therapy is a technique that allows for the modification of genes to treat or prevent disease and may become a viable way for doctors to treat a disorder without the need of drugs or surgery. This technology is still experimental, being only about three decades old with the first successful human trial occurring in 1990 when Dr. William French Anderson treated Ashi DeSilva for Adenosine deaminase deficiency (ADA deficiency), which is a genetic, metabolic disorder which causes immunodeficiency. Researchers are testing several approaches to gene therapy, which include replacing mutated, disease-causing genes with a healthy copy of the gene, inactivation a malfunctioning gene, and introducing new genes into the body that will help fight diseases. Over the last two decades, about 2,000 trials have been conducted or approved and future prospects for this technique are encouraging, include the engineering of human genetics in ways that may prove controversial and difficult to predict. This paper will explain how gene therapy works, what it has accomplished so far, its future and current hurdles, and what this all means for our species.

Though conceptually straightforward, the process of gene therapy involves biochemical problems of gene delivery, gene control and duration of gene action, each of which is a technical challenge.

Although gene therapy is a promising treatment option for a number of diseases (including inherited disorders, some types of cancer, and certain viral infections), but There are going to be many mistakes. What are we going to do with the mistakes?

Human gene therapy is when genetic material is introduced into human cells to treat a genetic disease. Instead of traditionally treating the symptoms, gene therapy aims to treat the disease’s root cause by directly altering genes and correcting defects. Therefore, gene therapy is only viable for certain diseases. Disorders from mutations in single genes are the most treatable, whereas disorders that involve many genes and environmental factors are trickier.

Despite the promise of such approaches, a number of difficulties remain to be overcome, the most important of which is the need for more efficient systems of gene delivery. No gene transfer system is 100% efficient, unless germ-line therapy is contemplated. During the past two decades, there have been major advances in our understanding of how cancer develops, proving that cancer has a genetic basis (2). A series of genetic abnormalities that accumulate in one cell may result in a pattern of abnormal clonal proliferation. Our growing understanding of the genetic basis of cancer offers new opportunities for the molecular prevention and treatment of cancer. There has been a

Gene therapy is an experimental treatment, which is used to replace mutated, improperly functioning genes with regular DNA. There are several gene therapy methods, most of which involve using a vector to transport the corrected gene into targeted cells. Retro viruses, adeno viruses, adeno ascosciated viruses and liposomes are commonly used as

Somatic gene therapy is a technique of genetic therapy wherein the ‘bad’ cells are identified and examined, and specially created cells are made then implanted into the body in order to thwart the effects of the disease, counteracting their damage. This therapy is limited as only the symptoms of the disease are controlled and technically the genetic footprint of the disease is still present and if the patient were to reproduce, the offspring would still possess a chance of retaining the mutation. Somatic genetic therapy is split into two groups: ex vivo gene therapy and in vivo gene therapy. Ex vivo genetic therapy is a technique where healthy cells are extracted
